1. IBM late to market with DDD products (Comvault's launched dedup, Symantec has PureDisk, Quantum and EMC are there with their products, Avamar does it at source, Data Domain in market for years), although HP is also late to market.
2. IBM a year late with SSDs in the DS8000 series. Can the system cope with their throughput? Uncertain, but I'll take a wait and see attitude here. I've never seen a non-IBM shop with a DS8000 and I don't expect this to change.
3. XIV snooze platform - a solution in search of a problem. At least now you don't have to have the Ford model T, aka "you can have any capacity you want as long as it's 80TB"
